What does VPN tunneling in SonicWall do?

VPN tunneling in SonicWall establishes a secure, encrypted connection over the internet, which is crucial for ensuring that data transmitted between remote sites or users and the organization remains confidential and protected from unauthorized access. This secure channel allows users to send and receive data as if they were directly connected to the organization's internal network, thus providing a safe path for sensitive information across potentially insecure networks like the internet.

The use of encryption within the tunnel protects the data from eavesdropping and tampering, which is a major advantage in today’s cybersecurity landscape. VPN tunneling is essential for remote workers, as it allows them to securely access resources as if they were on-site, thereby maintaining productivity while also safeguarding company data.

Other options focus on aspects that are not the primary function of VPN tunneling. While creating virtual networks, optimizing bandwidth, and enhancing local area network performance may be important for overall network management, they do not specifically pertain to the secure communication capabilities that VPN tunneling provides.
